fix(pause-point): stop resuming Play for a marker that already hit - #2553
Conversation
A wait whose marker was already hit at wait start settles on that recorded hit at its very first poll, because only continuous/trace markers get a new-hit baseline. --resume-play still ran before that poll, so `await-pause-point --id <X> --resume-play` restarted the game and then reported the old hit as a fresh success: the response said Unity was paused while control-play-mode Status showed IsPaused=false. A --trigger given alongside was dispatched into the running game for the same reason. The arm-confirmation query now recognizes that shape and performs neither side effect. The recorded hit is still returned, with ResumePlayResult carrying a new Skipped field (Resumed=false, no Error, so the wait still reads as the success it is) and TriggerResult carrying a matching not-dispatched Error. Already-hit continuous/trace markers and enable-pause-point --await are unaffected: both legitimately need the resume to reach the hit they are waiting for. Test stubs that answered the arm-confirmation query with an already-hit marker while asserting resume/trigger behavior now answer it with an armed, unhit marker, which is the state those scenarios actually describe.

…me message The skip message and reference doc asserted that Unity stays paused by the recorded hit, but the marker may have been resumed manually before this wait started, so state only that Play Mode is left untouched. Claude-Session: https://claude.ai/code/session_01XbhSMKK4LFud57iAmowDz7

Declining: the not-armed path already reports "trigger was not dispatched: ..." through TriggerResult.Error, and the Explanation comment in pause_point_trigger.go states that callers treat Error as "the trigger never ran", which is exactly this case. A separate Skipped field on TriggerResult would split the same meaning across two fields; ResumePlayResult.Skipped exists because Error there makes the wait treat the resume as failed and suppresses the trigger, which has no analogue on the trigger side.
…able --await Three review findings on the skipped-resume path. The skip path discarded the arm response that proved the marker had hit and let the poll loop re-query from an empty snapshot: a marker cleared or expired in between was then reported as that other state, and a transient query error polled on until the timeout — so the wait did not return the recorded hit as-is. The pre-wait stage now returns its outputs as a struct carrying an optional immediateHit, and waitForPausePoint answers with that response directly instead of entering the poll loop at all. The skip rule no longer excludes markerJustEnabled. enable-pause-point --await --resume-play against a per-frame line can see Hit at its own arm confirmation, and that hit settles the wait with no baseline, so resuming there produced the same "reports a hit while the game runs" inconsistency. The rule is now simply "the arm response already settles the wait": Status is Hit and decidePausePointNewHitBaseline gave no baseline. The already-hit test stub answered Hit to every query, so it could not tell an implementation that used the arm response from one that re-polled. It now answers once and fails the test on any later query. Claude-Session: https://claude.ai/code/session_01XbhSMKK4LFud57iAmowDz7

… output count The reference sentence claimed already-hit continuous/trace markers always resume, which contradicts the just-enabled case described one sentence earlier; the struct comment counted six outputs after a seventh was added.
